构建值得信赖的生成式AI需要在用户体验、强大安全性和一种专有的运营流程之间取得平衡,这种流程被称为 LLMOps。
1. 信任体验
在设计AI界面时,我们必须平衡四大用户体验支柱:可用性、可靠性、可访问性和愉悦感。最终目标是实现一种 信任平衡:
- 不信任: 当用户因性能不佳或缺乏透明度而拒绝使用系统时。
- 过度信任: 当用户对AI的人类化程度抱有不切实际的期望,并且未能验证其输出结果时。
提供 可解释性——即对AI如何生成特定输出的透明度——对于缓解这两种极端情况至关重要。
2. AI安全与漏洞
生成式AI引入了独特的安全威胁,传统网络安全框架必须加以适应(例如,使用MITRE ATLAS或OWASP LLM十大风险):
- 数据污染: 通过操纵训练或检索数据来破坏模型的完整性(例如,标签翻转、特征污染或数据注入)。
- 提示注入: 恶意操纵用户输入,以绕过安全防护机制,迫使模型执行未经授权的指令。
3. LLMOps生命周期
管理生成式AI应用需要一个专门的运营流程:
- 构思阶段: 使用PromptFlow等工具进行快速原型设计和假设测试。
- 构建阶段: 通过 检索增强生成(RAG) 或微调,使其连接到经过验证的数据。
- 部署阶段: 持续监控诸如“真实性”(诚实性)和延迟等指标。例如,真实性可表示为 $G = \frac{\text{已验证事实}}{\text{总声明数}}$。
教学摩擦
有意在用户界面中引入“摩擦”(如免责声明或必经的验证步骤),提醒用户正在与AI交互,有助于管理预期并减少过度信任。

Question 1
What is the primary risk of "Overtrust" in a Generative AI system?
Question 2
Which security threat involves compromising the training or retrieval data to trigger specific model failures?
Challenge: Medical AI Assistant
Apply UX and Security principles to a high-stakes scenario.
You are designing an AI assistant for a medical firm. You must ensure the data is safe and the user knows the AI's limits.
Task 1
Implement a design element to reduce overtrust.
Solution:
Add a disclaimer or "Instructional Friction" that requires the user to acknowledge the AI can hallucinate and that outputs should be verified by a medical professional.
Add a disclaimer or "Instructional Friction" that requires the user to acknowledge the AI can hallucinate and that outputs should be verified by a medical professional.
Task 2
Define a metric to measure if the AI is making up facts.
Solution:
Implement a "Groundedness" or "Honesty" metric to compare the AI's outputs strictly against a verified medical knowledge base (e.g., using RAG).
